When a Graph API encounters an error, how can I extract the HTTP status code in C#?

I assume use are using the graph sdk and not the rest api. See docs for getting the response code:
https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/main/docs/errors.md
You are absolutely right, I am using Graph SDK.
But I am puzzled - consider the following piece of code:
try
{
// Upload the file
var uploadResult = await fileUploadTask.UploadAsync(progress);
sb.AppendLine(uploadResult.UploadSucceeded
? $"Upload complete, item ID: {uploadResult.ItemResponse.Id}"
: "Upload failed");
}
catch (ODataError ex)
{
sb.AppendLine($"ODataError uploading: {ex.Error?.Message}");
sb.AppendLine($"StatusCode: {ex.ResponseStatusCode}");
}
catch(ServiceException ex)
{
sb.AppendLine($"Service exception: {ex.Message}");
sb.AppendLine($"StatusCode: {ex.ResponseStatusCode}");
}
catch (HttpRequestException ex)
{
sb.AppendLine($"HttpException: {ex.Message}");
sb.AppendLine($"HttpRequestError: {ex.HttpRequestError}");
sb.AppendLine($"StatusCode: {ex.StatusCode}");
}
catch (Exception ex)
{
sb.AppendLine(ex.Message);
}
finally
{
result.Text = sb.ToString();
}
If I disconnect the Internet connection while it is uploading the file, it throws HttpRequestException with
Message: An error occurred while sending the request,
HttpRequestError = 0 (unknown),
StatusCode = null
Shouldn't it throw ODataError?
